최연희,Choi, Yeon-Hee Korean Academy of Community Health Nursing 2000 지역사회간호학회지 Vol.11 No.2

본 연구의 목적은 유방자가검진(BSE)의 지식정도, 훈련도, 숙련도 및 빈도와의 관계를 파악하고, BSE 빈도를 가장 잘 예측하는 변수를 결정하기 위함이다. 연구대상자는 미국에 이민 온 40세-60세 사이의 중년 여성 58명으로 와싱톤주의 시애틀과 타코마 지역에 거주하고 있었다. 연구도구는 미국암협회의 BSE 안내책자를 기초로 하여 개발하였다. 자료는 자가보고형 질문지를 이용하여 한국교회 4곳으로부터 연구의 취지를 설명하고 연구대상자들의 연구동의를 얻은 후 우편으로 질문지를 회수하였다. 자료수집 기간은 2000년 3월 6일부터 2000년 5월13일이었으며. 질문지 회수율은 77%이었다. 수집된 자료는 SPSS를 이용하여 Frequency, Percentage, Pearson correlation, Regression analysis로 분석하였다. 연구 결과는 주요 변수사이의 관련성에서 그 이전연구 결과와 대개 일치하였다. 대상자의 BSE 빈도는 년간 10회-12회 실행이 21.08%이였고, 전혀 실행하지 않는 정도가 4.80%를 차지했다. BSE 빈도와 관련변수와의 상관관계에서 나이는 BSE 빈도와 역상관 관계(r=-.289, p=.038)를 나타냈고, BSE 훈련에 대한 지도(r=0521, p=.000). BSE 지식에 대한 기술(r=.573, p=.000) 및 BSE 숙련도(R=.694 P=.000)는 BSE 빈도와 정상관 관계를 보였다. 회귀분석 결과는 BSE 빈도의 가장 유의한 예측변수로서 BSE 지식에 대한 기술(beta=.5813. p=.003)로 지지되었다. 이 연구의 의의는 지역사회간호사가 이민 온 한국 중년여성들의 BSE실행에 대한 이해를 높임으로 유방암의 조기발견에 대한 예방적 행위를 증진시키는 데 유용한 기초 자료로 제공될 것이다.

CA를 인증 경로 처리 작업에 참여시키는 새로운 인증서 검증 방안

최연희,박미옥,전문석,Choi, Yeon-Hee,Park, Mi-Og,Jun, Moon-Seog 한국정보처리학회 2004 정보처리학회논문지 C : 정보통신,정보보안 Vol.11 No.1

PKI를 채용한 대부분의 어플리케이션들은 사용자로 하여금 인증서 검증 작업을 수행하도록 한다. 인증서 검증 작업의 사용자 측 수행은 사용자 부담을 증가시키고 검증 속도를 떨어뜨려 전체적인 사용자 시스템의 효율성을 저하시킨다. 본 논문에서는 인증기관(Certificate Authority :CA)을 검증 작업에 참여시킴으로서 사용자 측 부담을 감소시킬 수 있는 새로운 형태의 인증서 검증 방안을 제안하였다. 따라서 제안한 방안은 새로운 검증 서버의 구현 없이 사용자 측의 검증 작업에 대한 부담을 감소시킬 수 있을 뿐만 아니라 검증 작업의 축소로 인해 검증 수행 시간을 향상시킬 수 있다. Most applications using the PKI allows a user to execute the certificate validation processing. The efficiency of user system can be declined by the user-side processing resulting the overhead and low speed of the validation processing. Therefore, in this paper, we propose a new certificate validation processing method can decrease the overhead on user by allowing CAs of the hierarchical PKI to participate in the validation processing. Therefore, our proposed scheme can not only reduce the considerable overhead caused by the user-side whole processing without a new implementation of the delegated server but also improve the time spent for the processing by the reduction of the validation processing job on user.

인증 경로의 유효성을 높이는 효율적인 인증 경로 설정 알고리즘

최연희,전문석,Choi Yeon hee,Jun Moon seog 한국통신학회 2004 韓國通信學會論文誌 Vol.29 No.12C

다수의 인증 경로가 존재하는 PKI 구조에서 인증 경로를 설정하는 것은 중요한 문제이다. 경로 설정은 다양한 검증을 통해 이루어지고 검증이 많을수록 경로의 유효성은 높아진다. 유효성 높은 경로의 선택은 경로 설정 및 검증 작업의 반복 횟수를 감소시킴으로서 고속의 인증서 검증이 가능하도록 하는 반면에 하나의 경로를 설정하는데 소요되는 시간 및 부담을 증가시킨다는 문제점을 가진다. 본 논문에서는 보다 적은 부합으로 경로의 유효성을 높일 수 있는 효율적인 인증 경로 설정 알고리즘을 제안한다. To discover a certificate path is a very important topic in the PKI with a lot of candidate paths. The certificate path discovery processing is executed via many verifications and as the number of verification times increases, the validity of the discovered path becomes high. The selection of the path with high validity provides high-speed certificate validation by reducing the number of repetition times of path discovery and validation processing. Otherwise, there is a problem that the speed and computation overheads are increased. In this paper, we propose an efficient certificate path discovery algorithm can make high the certificate validity with low overhead.

감자의 유전자은행에서 분리된 8.0 kb Eco RI 절편에 존재하는 2개의 단백질 분해효소 억제제 II 유전자의 염기서열을 결정하였다. 그 결과 이들 2개의 유전자는 약 1.5 kb의 간격을 두고 동일한 전사방향으로 배열되어 있었다. PI-II-8.0A로 명명된 제1유전자는 158개의 아미노산으로 구성된 암호화 부위가 GT와 AG로 둘러 쌓인 하나의 intervening sequence에 의해 나뉘어져 있었다. 이 유전자의 5' 근접부위에는 promoter 요소로서 TATAAA와 CAAT의 염기서열이 존재하고 있었으며 3' 비해독 부위에는 poly(A) 첨가신호로 작용하는 것으로 알려진 AATAAG의 염기서열이 존재하고 있었다. 이러한 사실로 미루어 보아 PI-II-8.0 A 유전자는 기능을 간직하고 있는 유전자로 생각되어 진다. 그러나 PI-II-8.0B로 명명된 제 2 유전자는 암호화부위에서 염기서열이 부분적으로 제거되어 있었으며 기능을 간직하고 있지 않는 pseudogene으로 생각된다. We determined the nucleotide sequence of two proteinase inhibitor II genes present on a 8.0 kb Eco RI fragment which was isolated from a EcoRI-partial genomic library of potato. It revealed that the two genes were present at the same transcriptional orientation with an intergenic region of about 1.5 kb long. The first gene (PI-II-8.0A) coded for an open reading frame of 158 amino acids which was interrupted at the position of codon 17 by an intervening sequence of 101 bp in size flanked with GT and AG. The 5' flanking region revealed the presence of two putative regulatory sequences, TATAAA and CAAT, while the 3' untranslated region contained the polyadenylation signal, AATAAG. These suggest that the PI-II-8.0A gene may be functional. The second gene (PI-II-8.0B), however, revealed the presence of several deletions at the coding regions, two of which disrupted the reading frame, suggesting that the PI-II-8.0B gene may be a pseudogene.

Breast cancer ranks as one of the major health problems of adult women. Studies have shown that Breast Self-Examination (BSE) is effective in detecting breast cancer in its early stages. To motivate women BSE practicing, a nonequivalent control group pretest-posttest design was conducted. Women 40 years or older who participated in the public education program for BSE from March 11 to April 6, 1996, were randomized in an experimental group(N=50) which received a letter about the Breast Cancer Risk Appraisal and in a control group(N=50) which didn't received a letter about the Breast Cancer Risk Appraisal. After 6 months, a follow-up phone survey was taken on all participants to measure the effectiveness of the intervention. Collected data was analyzed by one, two, and three-way ANOVA with an SAS program. The results are summarized as follows : 1. The level of the Breast Cancer Risk Appraisal of the subjects is high risk(17%), moderate risk(12%), boderline risk(14%), no increased risk (57%). 2. The intervention was effective in increasing the practice scores of BSE for women(F=5.12, P<.05). 3. BSE practice scores according to breast cancer risk appraisal level of the experimental group was not significantly increased after the intervention as contrasted with the control group (F=2.33, P>.05). 4. BSE practice scores according to educational level of the experimental group was significantly increased after the intervention, as contrasted with that of the control group (F=10.09, P<.001) .On the basis of this study it can be concluded that the Breast Cancer Risk Appraisal increases practice of BSE.

최연희,Choi, Yeon-Hee 한국지역사회간호학회 1997 지역사회간호학회지 Vol.8 No.1

Breast cancer ranks as one of the major health problems in adult women. The purpose of this study is to determine relationships among the practice of Breast Self-Examination(BSE) and the variables of cancer risk and other genernal factors. This knowledge may be helpful in designing a BSE educational program to promote breast self-examination on a regular basis. The study population included 205 women who live in K city. Personal interviews were conducted to determine the individual's breast self-examination behavior, the level of Breast Cancer Risk according to general factors as well as her reasons for not doing a breast self-examination. The collected data was analyzed with an SAS program The results were summarized as follows : 1. The level of Breast Cancer Risk of the subjects is as follows: high risk(9%), moderate risk(11%), boderline risk(12%), no increased risk (68%). 2. There was no difference in the practice of BSE between women who were at high cancer risk and at no increased cancer risk. 3. BSE practice levels according to general foctors were significantly related to the residence and the level of education of the subjects. The performing of regular breast self-examination in urban areas was 7% and in rural areas was 0%. Regularly practiced breast self-examination in women with a low education was 5% and in college educated women, it was 29%. 4. BSE education was significantly related to the residence and the level of education of the subjects. The majority learned BSE through 'a magazine or journal'. 5. The reason of the majority of women did not perform a regular breast self-examination was, 'Didn't know the BSE technique'. On the basis of this study it can be concluded that the development of a BSE education program is needed to help women perform the examination correctly.
